Scope of Application Automotive Brake Fluid Detector is suitable for most vehicles. It checks the health status of DOT-3, DOT-4, DOT-5.1 brake fluids and most synthetic brake fluids. It is highly convenient for personal use and broadly applied in individual workshops, repair factories, and dealer workshops. Precision test and universal probe The detector features a highly sensitive and precise probe that quickly and accurately detects DOT-3, DOT-4, DOT-5.1 brake fluids and most synthetic brake fluids, with results in seconds. The gooseneck probe provides flexible detection, making the process more elastic and efficient. The probe top includes a flashlight so you can observe the color of the brake fluid if needed. Easy Instant Read and Alarm Combined with a high-sensitivity probe, high-resolution screen, and audible alarm, results are displayed instantly. The large, backlit display remains easy to read in sun or night, and the device operates reliably in different environments. When the brake fluid triggers a water content alarm, you will be reminded to change the brake fluid. Premium quality and ergonomic design The unit features a textured, compact body for a comfortable grip. The gooseneck surface is oil- and oxidation-resistant and not easily corroded. The control panel is simple and easy to use. The probe top with a flashlight allows color observation of the brake fluid if needed. Use scenarios - Home car maintenance: quick, reliable check of brake fluid health before long trips, ensuring DOT-3, DOT-4, DOT-5.1 or synthetic fluids are in acceptable condition. - Independent repair workshop: efficient diagnostics during routine brake service, enabling fast decisions on fluid replacement. - Dealership or repair facility: routine brake fluid status checks in service bays, supporting quality control and customer confidence.
